Whenever I go on v4 my buddy list deletes
 

Ok so whenever I go on v4 my graal buddy deletes and changes all my buddys to people I dont even know. How can I fix this?

Try deleting buddyaccounts.txt.

When you delete people from your buddy list (right click -> uncheck Buddy) then they are reappearing after the next login?
Eventually try to use different options for the playerlist? By default 'Load buddy list from server' is enabled, you shouldn't have problems with that though except the account is shared.

Does more than one person play Graal on that computer?
Not account sharing, you silly Stefan, computer sharing. :p

Or account sharing...Had the same problem when Velox hacked my acc...just disable the "Load buddy list from Server" option.

Nope im the only person that plays graal on this computer and my account isnt shared I have the e-mail and e-mail pass.

Change your password and see if it happens again?

I tried that already.
